It might sound like a bit of a cliche, but planting trees is by far one of the most important gifts we can give back to the planet and to ourselves. Global warming is caused by a buildup of greenhouse gases in our atmosphere (such as carbon dioxide and methane), which traps heat on the planet. But trees have the ability to suck up carbon dioxide, which is why the Amazon and other forests are so important. If every person on the planet plants one tree, that amounts to nearly 7 billion new carbon sponges. You can plant a tree in your own backyard, or join a group.

1. Take a Hike

There is no better way to get back in touch with the Earth’s rhythms than to actually go outdoors and experience its many wonders. This Earth Day, why not take a hike or go for a bike ride? Maybe even go kayaking? The point is, get outdoors, breathe the air, feel the sun on your cheeks and absorb some vitamin D. Even if you live in the city and don’t have easy access to a lot of green space, you’d be amazed how even spending a short amount of time in an urban park will rejuvenate your soul.

2. Get Involved in a Community Garden

If you have never experienced the magic of rolling up your sleeves and digging up some earth, then now is the perfect opportunity. Gardening is a wonderful way to reflect on how much we depend on the earth for our survival. If you don’t have your own garden or you live in a city, don’t fret. A quick google search should lead you to at least one communal garden or rooftop garden and we’re almost certain they won’t turn down your help. Plus you’ll get to meet new people who love the planet as much as you.

3. Do a Home Energy Audit

Not everyone has their own home, but if you do, nothing tells the planet “I love you” more than a home energy audit. Since most of the world is still powered by fossil fuels, that means your home is too, and if energy is pouring out of it because of poor construction, you are inadvertently releasing unnecessary greenhouse gases into our atmosphere. Don’t feel guilty about it because it’s not your fault, but you can make a difference by calling up a certified auditing company to audit your home. They will tell you exactly what steps you need to take in order to tighten up your energy efficiency, like sealing windows and unplugging appliances.
